Investigators said Shane Stykes was no longer under investigation as a possible suspect in the fatal shooting of his wife, Brittany Stykes.

Their 14-month-old daughter, Aubree, was shot and wounded in the head but is recovering at Cincinnati Children's Hospital.

A second person of interest was also eliminated, investigators said, but no additional details were provided.

"I know that there's at least one other person out there that knows everything about this case and obviously, that's the shooter. There, generally, is going to be other people that that person either had with them or confided in," Chief Deputy John Schadle said.

Brittany Stykes was found shot to death last month in her Jeep, which had run off the road near Georgetown.

"We don't know exactly how far down that road she could have traveled after being shot or if this took place on a side road," Schadle said.

Her husband told a local radio station last week that there was no evidence that his wife had been robbed.

Shane Stykes told WLWT News 5's Alison Montoya that he's been an emotional wreck and won't stop until justice was served for the person who killed his wife.

Schadle said they do not have a motive for the shootings.

"In today's world, you have all those road rage incidents and we can't say 100 percent that's not what this was," Schadle said.

He said his daughter was still hospitalized but doing well.

"We, as a community and as a Sheriff's Office, want to solve this case and give Brittany and her family some closure and some justice," Schadle said.
